# How to Add Sound Effects (SFX) to Video Captions for Maximum Engagement In professional retention editing, **visual motion must always be paired with an audio trigger**. When a word bounces onto the screen accompanied by a subtle "pop" or "whoosh", the brain treats it as an event, resetting the viewer's focus. --- ## 🔔 Best Practices for Caption SFX: - **Never Overuse:** Add sound effects only to 2-3 key transition moments per 30-second reel. - **Volume Balance:** Keep SFX 10-15dB lower than your vocal track so it never overwhelms speech. - **Timing Alignment:** Snap sound effects 50ms before the word appears for organic psychoacoustic sync. Add sound effects easily in the [Editoria Studio](https://editoria.in/editor)!
